The ones I know for sure that you can't videotape are--
Magic Kingdom: Carousel of Progress and Stitch's Great Escape
Epcot: Universe of Energy (actually, this one is contradictory, because the preshow says no videotaping, but when you get into the theater it says "no external video lighting"), Honey I Shrunk the Audience, American Adventure
Disney-MGM: Star Tours, Rock 'n Roller Coaster, Tower of Terror, Who Wants to be a Millionaire (but it's closing in a few days), One Man's Dream
There are some other attractions that will say "no external video lighting"-- this usually means it's OK to tape as long as you don't use any camera lights or flip-out LCD screens.
Also, on some occasions, the CM may forget to tell you not to videotape. This seems to happen often on Tower of Terror.
You can take pictures on most attractions-- there are only a couple that don't allow it-- but most indoor attractions don't allow flash photography. Taking pictures without the flash on these attractions is usually OK if they come out.
